ROADWAYS SHUT DOWN FOR PROTECTION OF BLACK LIVES MATTER PROTESTS SUNDAY AFTERNOON NEAR THOUSAND OAKS MALL:

Sunday afternoon into the evening hours, Black Lives Matter protests were observed in the Thousand Oaks area near Hillcrest Drive and Lynn Road by the Thousand Oaks Mall.

A crowd of multiple hundred people were seen holding signs in protest of George Floyd's death in Minnesota. The crowds were being closely monitored by the Ventura County Sheriff's Department and the California Highway Patrol.

Dozens of officers and deputies were observed wearing riot gear, and shutting down area roadways to divert traffic and keep the protesters safe to practice their 1st Amendment rights. Protesters had reportedly taken up space blocking an on ramp to the 101 Freeway at one point, but were quickly pushed back from the area, according to reports.

The crowds, mostly made up of young people, were vocal, and could be heard chanting, "Black Lives Matter," at various points. Cars passing by the area could also be heard honking their horns.

The crowd overall was being peaceful in their demonstrations, and no arrests, damage to property, or looting in the area had initially been reported, however later on residents were reporting that tagging had taken place on signs and walls in the area.

By about 8:30pm, a large number of law enforcement officers had been leaving the area and reopening the roadways with the protesters also diminishing.
